Meanwhile, the park's moose numbers have fallen 28% the past couple of years. But there are still more than 1,300, which is above their long-term average.
TRAVERSE CITY, Mich. (AP) — The gray wolf population at Isle Royale National Park is healthy once more.
Scientists reported Wednesday it has reached 28, only a few years after it had fallen to two. Health problems from inbreeding had caused a steady die-off, leading officials to bring replacements to the Michigan island from the mainland. Michigan Technological University scientist Sarah Hoy says at least five litters of pups have been born since then.
